- 203 step VarÅ¡amovâ€“Edel lengthening with (r_i)Â = (2, 4 times 0, 1, 14 times 0, 1, 34 times 0, 1, 62 times 0, 1, 84 times 0) [i] based on linear OA(8⁴², 512, F₈, 16) (dual of [512, 470, 17]-code), using
  - 1 times truncation [i] based on linear OA(8⁴³, 513, F₈, 17) (dual of [513, 470, 18]-code), using
    - the expurgated narrow-sense BCH-code C(I) with length 513Â | 8⁶âˆ’1, defining interval IÂ =Â [0,8], and minimum distance dÂ â‰¥ |{−8,−7,…,8}|+1Â =Â 18 (BCH-bound) [i]

There is no (32, 48, 140968)-net in base 8, because

the generalized Rao bound for nets shows that 8^mÂ â‰¥ 22 301934 130549 421263 251113 288387 066009 173684 > 8⁴⁸ [i]
